Anyone install a Ring Pro directly to a transformer?



I currently have a Ring Video Doorbell connected directly to a new transformer in the attic. I now have a ring pro I would like to install directly to the transformer. I am reviewing the directions here and I am a little confused: It shows a wire they call the “advanced power kit” yet the wires I got with my pro look like the ones they call the “pro power kit” as shown below on this page:

So, I am a little confused on how to install this directly to a transformer. Also, can the “power kit” (whenever I figure out how/which it is) be installed inline or does it have to connect directly to the transformer. I have contacted Ring directly, but havent gotten a response yet. I am sure they will, but with 3 days off I was hoping to get this all hooked up, so I figured I would check here and see if anyone has done this.

The power kit sits between the transformer and doorbelll (installed inside the old chime hosing). This allows the previous chime to be wired in and triggered by the new doorbell.


I am not using the old chime or old transformer. I am connecting straight to a new transformer and trying to follow these directions:

They are very unclear (to me at least).

OK, I misunderstood. Do you have the part described? If so, the diagram looks pretty straightforward.


No, I have the one in the second video. They look nothing a like but they are referred to as the same. I will just wait for their slow customer service to get back to me :slight_smile:

Post a picture of the power kit that you have.


I’m having the same issue. It appears the the pro power kit is a newer version but I’m not 100% sure it should be cut and wired inline. When put in a door bell it is inline from the transformer so it should work.


That is what I got.


Yeah, I have no clue how to install this thing and I havent heard back from support in quite a few days to my inquiry.

The power kit pictured is the one that is used with a door chime (mine looks exactly the same).

You need to install without the power kit and, assuming that you have a fuse to put in line, use just one of the clips.

The power kit is only used to trigger the chime.


Just had the same issue. Just ignore the wires labeled front.

Is this how we’re supposed to wire it if we don’t have the advanced power cable to wire directly to a transformer for the ring pro?

I’m also attempting to connect Ring Pro directly to the door bell transformer without an existing mechanical doorbell. Based on my research, the square enclosed Power Kit (also known as the Night Vision Kit) is different than what is actually required, ie. the connector with the fuse casing, known as the Pro Power Cable which is not included in the box of your purchase. This Pro Power Cable needs to be requested from It does look exactly like the image in the instructions for connecting to the ‘Direct to Transform Wiring’ image in the instructions (ie. fuse casing in between the two red wires). This is what I’m going through at the moment with Ring’s support team, which is very good.
Hope this helps.

Your picture shows the incorrect connection for connecting straight to the transformer. The square Power Kit is meant to be connected to an existing mechanical door chime.

The connection directly to the transformer is not with the Pro Power Kit (the square unit), you need the Pro Power Cable (two red wires on either side of a fuse casing). The Pro Power Cable is not included in the box; you need to request this through the Ring Support/Help line or email. Hope this helps.

So I talked to tech support and it looks like this “Pro Power Cable” is basically a resistor that limits to 25-30 Ohms, limiting power to between 20-50 Watts. This is essentially this product:

It looks like you need to make sure you use a resistor like this. Your Ring may work for a while if you don’t, but you run the risk of shorting it due to too much power.

Tech support will send you one within a week if you request it.


“Unlike Ring Video Doorbell, installing Ring Video Doorbell Pro direct to a transformer does not require a resistor.”

Read the above here:

As you can see, the online product description seems to contradict what support told you. I wrote requesting the wire with inline fuse, but I’m still confused as to whether I need it.

Edit: Just as I sent this, I noticed I was confusing “resistor” with “fuse”. My bad.

Hi !
I bought this Ring Pro and it was quite difficult to understand how to connect it without an existent doorbell.
Finally I did some test and I learned.
1.- Transformer: The ring need 24v AC 1Amp, so if you have 110v you will need 110v -> 24v AC 1 Amp. If you have 220v, you will need 220v -> 24v AC 1Amp. Make sure the output power is AC and not DC. I’m Using a 220v -> 24v AC 1Amp.
2.- Power Pro Cable: You can ask for free a Power Pro Cable to the Support, but the Power Pro Cable is just a 1Amp Fuse. So you can buy this at any electrical store, is a very common fuse. You need to connect this fuse to one of the cables of the out (24v) of your transformer. This will prevent to burn your ring if there is a over current.
And thats all !
Good luck !

Hola !
Compre el timbre Ring Pro y fue muy dificil entender como conectarlo sin tener un timbre pre-existente.
Finalmente hice algunas pruebas y aprendi.
1.- Transformador: El timbre funciona con 24v AC 1Amp. Por lo tanto, si tienes voltaje de 110v, necesitas un transformador de 110v -> 24v AC 1Amp. Si tu voltaje es de 220v, necesitas uno de 220v -> 24v AC 1 Amp. Asegurate que el voltaje de salida sea AC (corriente alterna) y NO DC (corriente continua). Yo estoy usando un transformador de 220v -> 24v AC 1 Amp.
2.- Power Pro Cable: Puedes pedir gratis el Power Pro Cable al soporte de, pero basicamente es un fusible de 1 Amper. Esto es muy comun y facil de encontrar en cualquier tienda de electronica. Este fusible debe ir conectado en uno de los cables de salida (24v) del transformador. El fusible se quemara si existe una sobrecorriente evitando que el timbre sufra daño.
Eso es todo !
Buena suerte !

I hope this helps

I had the hardest times with getting the Ring Pro to work properly with my setup. It took me a couple of months to figure out the issue. I finally got them working.
